all whom it mag/concern: Y y

Be it known that I, ARTHUR H. PETERS, a citizen of the United States, residing at .Fort Wayne, in the county of Allen and State of Indiana, have vinvented certain new and useful Improvements in Gearingsfor Washing-Machines, of Ywhich the following is the specication. y

This invention, relates to Vgearing for washing machines, and particularly for a novel construction and arrangement whereby amore efficient washing action takes' place. l

It is an object of the'invention to provide gearing for washing machines` of compact and simple construction, `whereby an attached wringer may be driven efficiently and with -the minimum loss of power, and whereby the lid of the washing machine may be raised and lowered during thewashing operation Without sacrificing energy stored' up in the fly wheel. A .y

It is another ob 'ect to provide a vacuum washer and associated parts so constructed and arranged that the vacuum washer positively travels about inside the tub and covers substantially the entire bottom thereof in its direct operation so as to absolutely insure the treatment of all of the material in the tub. n l

Other objects and 'advantages of the invention will appear as the Adescription to follow proceeds.: I

In the drawings Figure 1 is an elevation of a washing maj chine constructed according to my invention. AFig. 2 is atop plan view thereof;

Fig. 3 is a cross sectional elevation.

Fig. 4 is an enlarged detail cross sectional view showing a portionv v of the operating mechanism. f

. Figl' is a bottom plan view of the dolly.

Fig. 6 is a fragmentary detail cross sectional view showing the valve construction.

` as indicated, and having bearings 9, to accommodate a vertical wringerv shaft, the con- 1 represents a washingk machine tub mounted upon legs 2, equipped'with a platform 3, upon which I may mount anelec# tric motor 4. A portion 5 of the tub is4 prolonged to provide asupport for the bearing 6.k In line withL the bearing 6', isa bearing 7 in a bracket 8 bolted to the top vof theY tub,

arm-tien beiegsuch ,that @Wieger .maybe mounted in its usual Vposition l0 and driven by a vertical shaft having bearings 9. The lid of the tub 1 1l is of usual construction and has its hinged line parallel to the line of the bearings 6v and' 7. Mounted` in the bearings 6 and 7 is a'shaft 12, having at one end the gearing 1K3 for vdriving the wringer and at the other end the gearing 14 ,carrying the stub'l, which is pivotally connected at one end with the pitman 17 and at its other end connected with the ange 18, upon thecasting 19, pivoted upon lthe stubl 20,'` progecting from the casting 20', `firmly bolt-Y ed to the side of the tub. The'cas'ting '19, Y

has sockets 21 for the reception ofthe han" dle 22. 5

The casting 20" hasy projecting' therefrom.-

a stub 23, upon which 'isf lmounted a flywheel 24, the rim of which is vadapted to receive a belt 25 so as to be capable of being driven by the motor 4. vIntegralwith the ,fly-wheel, isa small pinion 26in mesh with ythe gear 14, so that when not motor driven' the fly-wheel 24 serves as an energy storingv y device. The gear 14k drives "the outer idler of a pair of idlers 27 mounted on a stub pro jecting from the plate 28firmly bolted to the extended` portion 5 Yof the tub. Mounted upon the hinged cover, is a bearing plate Y30 carrying a pair of brackets 31 forming bearings for the horizontal shaft 32,carry' ing at one end the gear '33 meshing j with the inner idler 27 and/carrying at its opposite end the crankv29'. The bearingplate 30 has adjacent the center of the tub a. ver? v tical bracket 34, which provides a bearing at -35 for the reciprocatory and rotary shaft 36, which has another bearing at 35, in the bearing plate 30 and passes through the cover, as clearly shown.` The crank 29 has at its endl a cylindrical aperture 87, in

which is revolubly 'and4 slidably vmounted the plug 38, connected to the pin 39, firmly mounted in the arm 40, which is'revolubly mounted as by means of a blushing 41 on the shaftv36 and confined thereon between the tworigidly -mounted collars` 42 and 43."

Abovev the'collar 42, is ;loosely seated 'the compression -spring 44. At the bottom of the shaft 36,.is fastened the eccentric bos'sj y Y 105 prises a domel having lat its bottom'Y theY 45 upon the vacuum .washer 46, which'comperforated plate 47 secured therein :by

Srews, vsuch ,31S 48, 'taking' into '190559549 in' i the interior-of the bell or dome 46. Thev perforated plate has Washer wings 50 theref a ylatch 62 engaging with a notch in the cast-v on andV is provided with a plurality of apertures. The bell 46 is provided at its top with a plurality of yapertures 5l covered by a plate 52, provided with a-rubber or lother suitable washer 53 and mounted upon the end of the screw 54, which projects "through the dome v46,y a space being left' ing V20' 'bolted to the side of the tub. A spring operated plungerk 63 working in a recess in the bearlng p late 30'tends to forcel v the latch 62 outwardly and keep it in engagement with the notch. The purpose of these parts is to keep -thefhinged cover securely locked down yeven though the pressurejimposed upon the clothes by the washer head 46 be considerable.

` to pull vup the handle 61, whereupon .the

upper portion lof the cycle of the crank 29. v As the crank 29 ,moves through the lower portion of its cycle, theY shaftv36 is dropped a ain, and the spring 44 falls withfit, as" s own` in Fig. 4. Inaddition to this, the

hinged cover is released.

vIn operation, theiwasher vmay be ,driven either from the handle 2.2 or by the motor 4. In the first event, the flywheel 24 serves-as an energystoring device; in the second, it serves as aY -belt ,pulle to communicate power .to the washer. T e-gear 14 communicates power ineither event to the yidlers 27,

the inner of which drives the gear 33 thus .operating shaft 32 Vand crank 29. Since the arm 40 is confined against longitudinal movement on the shaft 36 by the collars 42,

the rotation ofthe crank 29 will cause the verticalreciprocat-,ion of the shaft 36. While thepcrank is at its highest position, however,

the spring 44 willl be compressed between the collar 42 and the bearing-g 35 at the top of the bracket 34, the parts being-so positioned as yto cause this, which means that increased pressure over and above that of the weight of the washer will be caused between the arm 40 and the collar 42. TInasmuch as thc washer head 46 is at this time lifted over and clear of the clothes in the tub, and little, if any, obstruction is presented to the revolution of the shaft 36, this increased pressurey between the .arm 40 and the collar 42 vwill result in the shaft 36 being rotated during the washer head 46 is in contact-with clothes beingr washed and therefore" rot-ationl is no longenpossible. The effectof the-,action abovedeseribed is thatk thefwasher head/.1.6 is

4 When itv is de -slred to raise the cover, 1tl 1s only necessaryk raised, partially rotated, and dropped again, always turning to a new position at the top of its stroke and going straight down thereafter upon the clothes. This pounder head walksV or steps about substantially the entire bottom of the tub and thus equally affects all yof themate'rial therein. n

The operation of the washer head itself is a vacuum one. As the head is lowered upon the clothes, air andsuds are. discharged through the apertures 5l under the valve plate 52, which is lifted by the out-rushing air, this lift being permitted by the .space between the head of .the screw 54and the-:top ofthe inner portion of the dom-e 46. When the pounder head isY raised, however, Athe plate 52 closes the apertures .511 andcauses :ai partial vacuum inside the dome 46,'-wvhfich positively draws suds, water and air through the clothes as the vacuum washer-nis raised,V thus increasing. the cleansing action of the machine byvacuum ,operation as well-as by mechanical shifting and strikingy of the clothes. f f.
